Based off of the bone structure of humans and snakes, which of the following can we conclude?

• Humans are an ancestor of snakes

• One of the ancestors of snakes had legs, which they no longer use

• Humans will eventually become snakes

• Snakes have legs that they still use

Why is the fossil record considered the strongest evidence for evolution?

• They provide physical examples of living things changing over time

• Fossils are very easy to find, making this type of evidence very common

• They show organisms developing from early stages of life until they die.

The similarities of the bones in the diagram provide evidence that---

• The organisms shown lived in the same natural envionrment

• The organisms shown may have developed from a common ancestor

• All vertebrate species have identical forelimbs

The fossil record help scientists

• better understand the kinds of organisms that lived in the past

• better understand how the environment has changed over time

• better understand how organisms have evolved over time

• all of the above

• homologous structures

• fossil record

Structures are similar in function but not in anatomical structure
EXAMPLE: bird wings vs. butterfly wings

• Vestigial

• Homologous

• Analogous Structures

• Embryonic

Homologous structures are ​ (a)   in structure but ​ (b)   in function

• similar

• different

As these embryos continue to develop, what will most likely happen?

• Develop new organs according to the nutritional requirements of each organism

• Share similar habitats

• Develop the distinctive characteristics of their own species

• Continue to closely resemble each other as adults.
